A Minimum Principle on Displacements and a Related NLP Formulation for the Elastostatics of Cable Systems
Behaviour of cable networks affected by geometric and physical nonlinearity combined, due to large displacements and cable slackening respectively, is investigated through a minimum principle on displacements. Relevant sign-constrained Non Linear Programming formulation, concerning algebraic or algebrized problems, is considered as the basis for numerical analyses. A significant example shows the successful match between the proposed approach and a suitable devised algorithm.
